Loss of recent memory after bilateral hippocampal lesions: memory and memories-looking back and looking forward.
In 1957, Scoville and Milner reported a series of case studies describing the nature of the memory defect they observed following bilateral surgical removals from the medial temporal region. The paper highlighted that extensive bilateral surgical excisions from the hippocampus and hippocampal gyrus resulted in severe and lasting memory loss; it also focused attention on these brain structures a...
متن کاملFactors affecting graded and ungraded memory loss following hippocampal lesions.
This review evaluates three current theories--Standard Consolidation (Squire & Wixted, 2011), Overshadowing (Sutherland, Sparks, & Lehmann, 2010), and Multiple Trace-Transformation (Winocur, Moscovitch, & Bontempi, 2010)--in terms of their ability to account for the role of the hippocampus in recent and remote memory in animals. Evidence, based on consistent findings from tests of spatial memor...

متن کاملBilateral Hippocampal Infarction as Etiology of Sudden and Prolonged Memory Loss
Sudden memory loss, with prolonged cognitive deterioration, clinically initially resembling a transitory global amnesia (TGA)-like episode, might be caused by ischemic stroke in the hippocampal regions. We report a patient with TGA-type sudden anterograde amnesia and normal head CT. Examinations revealed that the patient had several vascular risk factors and 3 tesla (T) head MRI showed ischemic...
متن کاملReversible hippocampal lesions disrupt water maze performance during both recent and remote memory tests.
Conventional lesion methods have shown that damage to the rodent hippocampus can impair previously acquired spatial memory in tasks such as the water maze. In contrast, work with reversible lesion methods using a different spatial task has found remote memory to be spared. To determine whether the finding of spared remote spatial memory depends on the lesion method, we reversibly inactivated th...
